About the Audi A3 Sportback 2024 boot
Behind the loading sill of the Audi A3 Sportback 2024, the boot floor drops 6¼″. The sill is 26⅜″ high, and the opening above it is 38¼″ wide with 24″ of clear height, which limits how tall a box can be as it goes in. The floor is 39″ wide at its narrowest and 30⅜″ long with the rear seats up, so it is wider than it is long. Fold them and it reaches 58⅝″, the limit for a box laid flat lengthways. Lift a heavy box with a second person, so you can lower it down the step instead of dropping it.
About the BRIMNES Cabinet with doors, white, 30 3/4x37 3/8″ package
Small box, serious weight. The BRIMNES cabinet packs 72 lb 7 oz into a single box of 39″ × 16¾″ × 6″, and something that compact and heavy is easy to underestimate. Lying flat, it sits on a patch of floor 39″ by 16¾″. The lift is where the care goes. Short as the box is, that weight is a lot to hold while you lean into the boot. Take it as a pair, knees bent and backs straight, and lower it gently all the way down rather than letting it drop the last bit.
